As a side-benefit, this add-on reduces Facebook CPU usage dramatically. I run several FB tabs in FF, each tab showing the “Discussion” page of one of many groups that I’m a member of. Before installing this add-on, each tab’s FB process would use 100% of a CPU… almost all the time. Killing and restarting had no effect - they would quickly ramp up to 100% CPU usage per page, and stay that way permanently. (You can see (and kill) facebook’s processes in firefox by navigating to about:processes.) This high CPU usage was a huge drag on performance of FF, and indeed the whole machine. After installing this add-on each tab is now using only a fraction of 1% of a CPU. So, not only does this add-on improve privacy and security, it also stops FB hogging my CPU. What was Meta doing with all that processing power, anyway?

It's awesome. I gave 4/5 because I would really need that I can manage cookie/session/cache per container too.

I love how after using this extension for a while the ads throughout facebook or instagram got so general instead of showing me a million ads about the thing I just recently searched for. Thanks Mozilla for letting us stand up against companies like Meta, I appreciate that.

Complimenti bravi.

I see it's a nice extension, but it can't fully blocked (~95%) because fingerprinting. Also why it don't list WhatsApp?

great. f###k meta

Trust is ok
